WITHDRAWN: Implant stability changes in dental implants installed by osseodensification and conventional methods: A randomized controlled study

Abstract

Purpose In this study, the osseodensification (OD) drilling technique was used to assess the impact of implant site preparation on implant stability changes during the osseous healing period, insertion torque (IT), and preparation time.Methods In this randomized controlled clinical study, a total of 20 patients received 40 dental implants (DI), which were divided into two groups at random: the first group (the study group), which received the implants using the OD drilling technique, and the second group (the control group), which received the implants using the conventional drilling technique. Prior to surgery, bone density was assessed by CBCT. The Osstell implant stability quotient (ISQ) was used to measure implant stability immediately following implant insertion as well as 6 and 12 weeks later.Results There was no statistically significant difference in primary stability between the groups (P-value 0.216). In contrast, at 6 weeks and 12 weeks postoperatively, the control group showed higher ISQ values (P-values 0.002 and 0.005, respectively). There was no significant difference in the (IT) between the groups (P-value 0.627). The preparation time was significantly longer in the study group compared to the control group (P-value 0.0001).Conclusion The OD drilling technique did not show a more favorable outcome regarding the implant stability changes, IT, and preparation time over that of the conventional approach and resulted in a significant drop in stability after 6 weeks postoperatively, making OD use for early loading questionable.
